The bottom of the lawn mower should be cleaned after each use to prevent tightening of
cut lawn, leaves, soil or other debris. If it accumulates, it will cause rust and the
performance of the machine will be affected.

Removing the knife, replacing it, sharpening
● When removing the knife for sharpening or changing, protect your hands with a pair
of thick gloves when holding the knife.
● Remove the HEX HD screw and the flat washer that holds the knife.
Machineeful: Periodically inspect the knife adapter for cracks, especially if
you hit a hard object. Replace it when needed.
When sharpening the knife, follow the original angle of the edge as a reference point. It
is extremely important that each part of the knife is sharpened equally to prevent knife
imbalance. The unbalanced knife will cause excessive vibration when the engine enters
speed. Before reinstalling the knife and knife adapter, lubricate the engine shaft with oil.
Make sure you have installed the face knife marked with the number down when the
machine is in the operating position.
